Development of C-band 2 000 W GaN linear solid-state power amplifier
This paper introduces an engineering realization of a C-band 2 000 W GaN high linear solid-state power amplifier. Using 32 GaN power transistor chips and using microstrip Gysel power dividers and waveguide power dividers/synthesis networks for power ...

ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

Comparing C- and L-band SAR images for sea ice motion estimation [PDF]
Pairs of consecutive C-band synthetic-aperture radar (SAR) images are routinely used for sea ice motion estimation. The L-band radar has a fundamentally different character, as its longer wavelength penetrates deeper into sea ice.

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

ABSTRACT Ewing sarcoma (ES) and rhabdomyosarcoma (RMS) are aggressive malignancies in children and adolescents where metastases impact prognosis. 18F‐fluoro‐2‐deoxy‐d‐glucose positron emission tomography/computed tomography (FDG‐PET/CT) and bone marrow aspirate and trephine biopsies (BMAT) are used to identify disease involvement.

ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Heterochromatin (C bands) in bovine chromosomes [PDF]
Metaphase chromosomes from cattle leukocytes were stained for constitutive heterochromatin. It was possible to demonstrate heterochromatin in the centromere regions of the autosomes but not of the X chromosome. The short arm and the centromere region of the Y chromosome were more faintly stained than the centromere regions of the autosomes.
